Computer Hardware
Chapter Computer Hardware ENCE EXAM TOPICS COVERED IN 1 THIS CHAPTER: ✓ Computer hardware components ✓ The boot process ✓ Partitions ✓ File systems COPYRIGHTED MATERIAL Computer forensics examiners deal most often with the media on which evidentiary data is stored. This includes, but is not lim- ited to, hard drives, CDs, DVDs, fl ash memory devices, smart phones, tablets, and even legacy fl oppies and tapes. Although these devices might be the bane of the examiner’s existence, media devices don’t exist in a void, and knowledge of a computer’s various components and functions is a must for the competent examiner. As an examiner, you may be called upon to explain how a computer functions to a jury. Doing so requires you know a computer’s function from a technical standpoint and that you can translate those technical concepts into real-world, easy-to-understand terms. As an examiner, you may also be subjected to a voir dire examination by opposing coun- sel to challenge your competence to testify. Acronyms are hardly in short supply in the fi eld of computing—some well-known and meaningful, others more obscure. Imagine being asked during such an examination to explain several of the common acronyms used with computers, such as RAM, CMOS, SCSI, BIOS, and POST. If you were to draw a blank on some obscure or even common acronym, picture its impact on your credibility. Some acronyms are difficult to remember because their meaning is often obscure or meaningless. A good example is TWAIN, which stands for T ech- nology W ithout a n I nteresting N ame. -

CIS 4360 Secure Computer Systems Attacks against Boot and RAM Professor Qiang Zeng Spring 2017 Previous Class • BIOS-MBR: Generation I system boot – What BIOS and MBR are? – How does it boot the system? // Jumping to MBR – How does multi-boot work? // Chain-loading • The limitations of BIOS and MBR – Disk, memory, file system, multi-booting, security, … • UEFI-GPT: Generation II system boot – What UEFI and GPT are? – How does it boot the system? // UEFI boot manager – How does multi-boot work? // separate dirs in ESP CIS 4360 – Secure Computer Systems 2 Limitations of BIOS-MBR • MBR is very limited – Support ~2TB disk only – 4 primary partitions at most (so four OSes at most) – A MBR can store only one boot loader • BIOS is very restrictive – 16-bit processor mode; 1MB memory space (little spare space to accommodate a file system driver) – Blindly executes whatever code on MBR CIS 4360 – Secure Computer Systems 3 UEFI vs. BIOS • Disk partitioning schemes – GPT (GUID Partition Table): part of UEFI spec.; to replace MBR – MBR supports disk size 232 x 512B = 2TB, while UEFI supports much larger disks (264 x 512B = 8,000,000,000 TB) – MBR supports 4 partitions, while GPT supports 128 • Memory space – BIOS: 20-bit addressing; UEFI: 32-bit or 64-bit • Pre-OS environment – BIOS only provides raw disk access, while UEFI supports the FAT file system (so you can use file names to read files) • Booting – BIOS supports boot through boot sectors (MBR and VBR) – UEFI provides a boot partition of hundreds of megabytes (and boot manager and secure boot) CIS 4360 – Secure Computer Systems 4 Previous Class How does dual-boo-ng of Linux and Windows work in UEFI-GPT? Each vendor has a separate directory storing its own boot loader code and configuraon files in the ESP (EFI System Par--on). -

Veritas System Recovery Disk Help
Veritas System Recovery Disk Help About recovering a computer If Windows fails to start or does not run normally, you can still recover your computer. You can use the Veritas System Recovery Disk and an available recovery point or a virtual disk that you created from a recovery point. Note: If you can start Windows and the drive that you want to restore is a non-operating system drive, you can restore the drive within Windows. The Veritas System Recovery Disk lets you run a recovery environment that provides temporary access to Veritas System Recovery 21 recovery features. For example, you can access the recovery features of Veritas System Recovery 21 to restart the computer into its previous, usable state. About recovering a Unified Extensible Firmware Interface (UEFI)-based computer Veritas System Recovery Disk lets you recover the computers that use the Unified Extensible Firmware Interface (UEFI) standard. However, consider the following points when you recover UEFI-based computers: • You must start UEFI-based computers using the 64-bit version of Veritas System Recovery Disk. • When you boot a UEFI-based computer, ensure that the system drive and the boot drive are located on a GPT disk. Similarly, when you boot a BIOS-based computer, your system drive and boot drive must be located on an MBR disk. • You cannot restore backups of the boot partition and the system partition of UEFI-based computers to BIOS-based computers. Backups of UEFI-based computers must be restored to GPT disks. Similarly, you cannot restore backups of the boot partition and the system partition of BIOS-based computers to UEFI-based computers. -
UEFI, Booting & Partition Management
UEFI, Booting & Partition Management Kelvin Cording July 2018 Unified Extendible Interface (UEFI) • Modern computer and Windows are moving away from the traditional MBR based boot- up processes to hardware and software using UEFI • Win 8 introduced UEFI • If Windows 8 is already installed using Legacy BIOS, it can't be converted to UEFI. A new OS installation is required. Understanding a computer boot up process When you hit the power button of your PC, an execution begins that will eventually load the Operating System into memory. This first execution depends on the partition structure of your hard disk. We have two types of partition structures (or formats): MBR and GPT. The partition structure on a drive defines three things: • The structure of data on the drive. • The code used during startup if a partition is bootable. • Where a partition begins and ends. MBR -Master Boot Record GPT Globally Unique Identifier Partition Table = GUID Partition A comparison of GPT and MBR partition structures A comparison of GPT and MBR partition structures (2) Max partition size in MBR is ~2TB whereas in UEFI it is ~9 ZetaBytes One zettabyte (1021) is approximately equal to a thousand exabytes or a billion terabytes. MBR can have at max 4 primary partition whereas GPT can have 128. MBR can store only one bootloader whereas GPT has a separate dedicated EFI System Partition(ESP) for storing multiple bootloaders. The MBR Boot Process Before the BIOS can detect the boot device, it goes through a sequence of system configuration functions starting with: • Power-on-self-test. • Detecting and initializing the video card.
